step back through previous Find Next results

Hi
I have a set of membership records which have data input via a form. When looking for a particular record I use the standard CTRL+F on the whole record set from the Form view, and move through the results using the Find Next button. Is there a way to move back through the records when I have got to the end of the results. eg. there may be numerous members with a surname Smith and I can move through the Smith records by using Find and Find Next actions but if I have move past the record that I want is there a way of stepping back through the records to a previous Find Next record?
Apologies if this is a really obvious question
